This invention relates to musical instruments, and has, more particular reference to a violin bow.

The primary object of this invention is to I provide an improved means for securing the ends of the hair strings of a violin bow to the frog and enlarged end of the bow stafl, whereby the horse hair strings of the bow may be readily removed or re laced without any possibility of damage eing inflicted upon the bow.

A still further object of the invention is to provide means for securing the ends of V the horse hair strings of the bow to the frog 16 and staff end, whereby the removal or replacement of how strings may be accomplished within the period of but relatively short time and a cheaper and less inexpensive manner than in the former methods as have been heretofore in vogue.

A still further and very important'objeet of the invention is to provide a pairof especially designed clips adapted for receiving the knotted ends of the bow strings one clip 26 of the pair being adapted for engagement with the conventional frog of a violin bow, and the other clip adapted to engage with the enlarged lateral end of the bow staff;

n Another important object of the invention 15 to provide a device of the character above mentioned which is comparatively simple in construction, strong, thoroughly reliable, practical and eflicient in use and operation,

7 and otherwise well adapted for the purpose '35 ntended. 7

Other objects and advantages of the inven tion will become apparent during astudy of the following description, taken in connection with the accompanying drawings wherein':

Figure-1 is a side elevational view of a violin bow constructed in accordance with the present invention and showing the mannerof applying my invention thereto.

Figure 2 is a longitudinal sectional view taken through the frog and clip applied thereto.

Figure 3 is a similar view taken through the enlarged lateral end of the bow and the clip applied thereto.

Serial No. 394,200.

Figure 4 is a perspective View of the ,shoe or clip adapted to be engaged with the frog of the violin bow. I I t Figure 5 is a similar view of a slipper member adapted to be engaged with'the enlarged lateral end of the bow staff.

With reference more in detail to the drawings, it will be seen that we have illustrated a conventional violin bow comprising the usual stafi 5 which staff 5 terminates at one end in a relatively large lateral end portion 6. At its opposite end slidably mounted on the staff 5 is a conventional frog 7, while the reference character 8 designates the adjusting knob for actuating the frog 7.

As comprehended by the present invention, the enlarged lateral end 6 of the bow staff is provided with a socket 9 formed therein and extending, inwardly from the lower end of said portion 6. A slipper member designated generally by the reference character 10 comprises a base 11 and a toe member 12, which toe member 12 is adapted, being in the nature of a socket, to receive the laterally extending toe portion 13 of the staff end 6, so that the base 11 of the slipper member extends along the entire bottom face of said end 6 as clearly shown to advantage in Figure 3. On opposite longitudinal edges thereof the base member 11 is provided with upstanding spring like fingers or retaining flanges 1414 adapted to frictionally engage the end 6 on opposite sides of said end for retaining the slipper member 10 thereon. Further, the base 11 is provided rearwardly of the toe 12 with a hole or. aperture 15 adapted to register with the socket 9. At the end remote from the toe 12 the slipper 10 is provided with a sleeve 16, the material forming the base 11 at said end being provided with relatively long extensions on opposlte sides thereof, which extensions are bent downwardly as at 17 and then inwardly in parallelism to the base as at 18 the end portions 18 having their adjacent edges disposed in abutting relation and thus forming with the base 11 the said sleeve 16.

The horse hairs forming the bow strings 19 have their ends suitably knotted as at 20 and 21, respectively. One end of the bow strings 19, which for convenience designated as at 21, is adapted to pass through the aperture 15 in the base oi? the slipper member 10 for reception into the socket 9, it being understood that the knot 21 is of suliicient diameter as to prevent the pulling of the bow strings through the aperture 1.5 when the knotted end 21 is retained in the socket. The horse hairs ot the bow strings 19 are then passed through the sleeve l6, and at the other end bow string is pass d through a similarly 'lormed sleeve 22 formed on the for :ard end of the base n1cmber 23 of a frog engaging shoe member designated generally by the reference character 24.

The frog engaging member or shoe 2 is provided on its base portion 23 in close proximity to the sleeve 22 with an aperture to which the other end of the bow strings 19 is passed so that when knotted as at 20 this said end of the bow strings cannot be pulled through the aperture or opening 25. Secured to the base member 23 ot the shoe 2% adjacent the opening 25 is a send-circular band 26 formed oi metal or any other snitable material which is adapted to be disposed about the toe portion 7 of the fro 7. The base tit-l extends along the bottom or the frog 7 for the full length oil the frog, and at its rear end said base 233 merges into a relatively wide heel 27 'l orn'iing a seat for the reception of the rear lower end or corner ot the frog 7. In forming the heel of the shoe 24 the bare is enlarged at its rear end and the enlarged. end 27 of the base 23 has a flange 28 extending transversely of the base and along opposite sides thereof at the extreme end of said base for engaging with the rear end and opposite sides of the frog 7.

In actual practice, the ends of the bow strings 19 are passed through the openings 1! and 25 respectively, of the slipper member 10 and shoe member 24, which ends are then knotted at 20 and 21. The slipper member is then disposed upon the lateral end portion 6 of the staff 5 in the manner before eX- plained. The knot 8 is then rotated so as to move the frog 7 longitudinally oi the stall 5 in ardly toward the end 6 and the shoe member 2st is then applied to the frog 7 in the following manner; the band 26 is first slipped over co-extension 27, after which the base member 23 of the shoe pressed upwardly against the bottom face of the frog 7 so that the lower left hand corner of the frog 7 is received in the heel of the shoe, whereby the flange 28 engages the frog 7 to bear against one vertical end edge of the frog and against the opposite side faces of the frog as suggested in Figures 1 and 2. The knob 8 may then be rotated in the opposite direction for moving the frog 7 rearwardly of and away from the stati end 6 thus drawing taut the horse hairs of the bow strings 19.

The mechanism connecting the operating knob to the frog 7 is CODVOTltiOHHl, Forming no part of this invention and, therefore, it is deemed that a detailed showing of such un necessary and would be superfluous.

It is believed that from the foregoing description taken in connection with the accompanying drawings, a clear understanding of the construction, operation and utility of an invention of this nature will be had. A more detailed description thereof is, therc'lm'c, deemed unnecessary.

Even though we have herein shown and described the pre'l errcd cmbodin'icnt of our invention, it is to be understoml that the same is susceptible to certain changes itallin g within the scope of the spirit of the invention as herein described, it being further understood that we do not wish to limit ourselves other as would be required in view of the state of the prior art and the scope of the appended claims.
